The clutch shots. The late charge. An electric birdie putt on the 18th hole at Bay Hill.

Yep, Tiger Woods is back.

With those familiar back-nine heroics and a putt most everyone knew he was going to make, Woods holed a 15-footer for birdie to win the Arnold Palmer Invitational in Orlando for his first victory since returning from knee surgery.

Woods closed with a 3-under 67 for a one-shot victory over hard-luck Sean O’Hair, matching his largest comeback on the PGA Tour.

“It feels good to be back in contention, to feel the rush,” Woods said. “It’s been awhile, but God, it felt good.”

Just like last year, when Woods made a 25-foot birdie on the final hole at Bay Hill for a one-shot victory, he delivered a high-charged celebration. Instead of slamming his cap to the ground, he turned and ran into the arms of his caddie, who lifted him off his feet.

Then came the meeting with the tournament host.

“What was it I told you last year?” Palmer said with a wide grin.

Palmer has seen enough of Woods to know what to expect. Woods won at Bay Hill for the sixth time, the third PGA Tour event he has won at least that often.

This one was special.

Woods had not been atop the leaderboard since he won the U.S. Open in a 19-hole playoff last June.

With two indifferent results at World Golf Championships, there were questions whether he would be ready for the Masters in two weeks. Not anymore. He rallied from a five-shot deficit and delivered one crucial shot after another in fading sunlight.

It was the third time Woods has won at Bay Hill with a birdie on the 72nd hole.

O’Hair made only one birdie and closed with a 73, but he steadied himself along the back nine until a crucial mistake on the 16th hole, when he went at the flag with Woods in the rough. His 7-iron came up short and into the water, leading to a bogey.

“I think what happened is when the sun was going down a little bit, I guess that kind of proved to me that the ball wasn’t quite going as far,” O’Hair said.

He might be right, for Woods ran into the same problem a hole later. He posed over a 4-iron that he thought was flush. This one plugged under the lip of the front bunker, and Woods made bogey to fall into a tie.

That set up the dramatic finish with only minutes of daylight remaining, thanks to a two-hour rain delay in the morning.

Woods finished at 5-under 275 and won $1.08 million for his 66th career victory. Only once in his career has Woods failed to win a PGA Tour in the three months leading to the Masters, but more Bay Hill magic took care of that.

Zach Johnson shot 69 and finished third.

Woods was running out of holes until he came up with two clutch putts, the kind he has made throughout his career.

“It’s like Stevie was saying out there,” Woods said of caddie Steve Williams. “This feels like we hadn’t left. You just remember how to do it. It hasn’t been that long for me, but you just have that feel of what to do. And it’s a matter of getting it done.”
